girlfriends birthday coming up and I thought I'll spruce up her quad fish with some nice girly fins, have looked on the net but seems shapers only make FCS compatible.
DL uses them in his fish - from what he's said to me he's had to import them from the states (not cheep at the moment) which is the same thing that I run into with pro-box you can try:
www.finshop.com.au www.lokboxfins.com - they sell direct
DL might be able to tell you where he got his if you PM him
